7 My said invention relates to improvements in the flushing arrangementof water closet bowls designed more particularly for use in connectionwith boats -where the closet is frequently located below the level ofthe water surrounding the boat hull, or where such level is raisedtemporarily above the closet by wave action, listing of the boat, etc.,and the invention aims to provide a construction which will bemore'eihcient in its flushing action which will be capable of ready adjustment to accord with changed conditions of use, which may be readilycleaned should it become clogged, and which will be proof againstflooding from backing up of water in the discharge pipe, due to superiorelevation of the exterior water.

With these and other objects in view, the invention comprises the novelconstruction hereinafter described, that which constitutes the inventionbeing defined by the claims ap pended hereto.

An embodiment of the invention is illustrated in the accompanyingdrawings in which:

Figure 1 is a longitudinal vertical section on line 11 of Fig. 2, and vFig. 2 is a section on line 2-2 of Fig. 1. Fig. 3 is a section on line33 of Fig. 2. Figures 4, 5 and 6 are sectional detail views of the checkvalve at the top of the discharge pipe.

drawing, the numeral 3 designates the bowl having its rim provided withthe circumferential passage or conduit 3 for the flushing water which isdischarged into the bowl through the ports or openings 3 The bowl is.

formed with a horizontal base extension 3 40 containing the bowldischarge passage which extension has a flat shelf-like portion on whichis seated a bed portion 4: which has a passage or opening 4 which alineswith the upturned end or mouth of the bowl discharge passage. Mounted onthis bed plate l is a discharge pipe 5 of substantially inverted Ushape, the leg 5 of which communicates with the passage 4 in the bedplate while the other leg 5 alines with a passage 4 in the bed plate bywhich it is connected to the Referring by reference characters to thissewage disposal pipe 6. The discharge pipe 5 is extended upwardfor adistance suflicient to ensure its upper bend being always above thelevel of the water outside the boat hull. The distance to which it isextended upward may, of course, be varied according tothe situation ofthe closet in the boat relative to the water line.

The passage 4* is preferably contracted towards its top to form a valveseat provided with a suitable packing indicated at 7 to coact with avalve 8, preferably of the ball type, which is located in a ballcontaining chamber 5, formed in the legportion 5 and communicating withthe upward dischargepas sage therein by an outlet port 5 of lessdiameter than the ball valve, whereby the latter is retained within thevalve chamber. This valve prevents backing up of water in the dischargepipe due to location of the closet llo elzilow the water line or waveaction and the Check valves, however, can never be de pended on againstleakage in pipes used for conduction of sewage, but by'reason of theU-shaped' bend of pipe 5 being carried well above the water line, if thevalve should fail to seat for any reason, flooding of the bowl due tobacking up of outside water iseffectually prevented. 3

It will be observed that if the U-shaped pipe 5 were left full of wateratthe completion of a flushing operation and the check valve fail toeffect a liquid tight contact with its seat, there would be danger ofthe said pipe 5 5 acting as a siphon and" drawing water in a reverse"direction with resultant flooding of the seat. To avoid this, I providethe said pipe 5 with a check valve 5 located at the top of the bend andcomprising a pipe section w tapped into the bend of pipe 5 and having avalve chamber ac provided with a ball valve m designed to permitentrance of air but exclude egress of'water.

The upward discharge leg is more upwardly flaring to secure a Venturitube effect, and

a jet passage 5 discharges water centrally into the lower end of the.said leg 5 in line with the axis thereof, with an ejector action which1s strong enough to force the'water and sew-' 1.00

7 age upward through the discharge pipe'f and out through pipe 6 intothe outside water, and to evacuate the contents ofthe bowl through saidpipesl The bed portion i is formed hollow and receives water from achamber 5 -formed on the descending legge", the lower end of whichcommunica-tesbyalined ports with the hollow interior of the bed plate.lvater is sup plied to chamber 5 bypipe.8 .connected to any suitableflushometer or device not shown.

' vThe jet passage 5 is in communicationwi th I the hollow interior ofthe bed plate 'as shown at the left of Fig. 2, the water thus'suppliedaction.

through this jet serving to start the siphon 'T hei member 5 is providedwith another passage or chamber 6 which communicates at its lower endwith thehollow interior or Water space otthe bed plate 4 and at its uplper end with the water chamber 3 in the bowl rim. Said upper end isshaped to form ber5 is shaped to-provide an enlarged part which may beoit-theball type, provided with a valve seat with which cooperates avalve 9 regulating-screw 10 whereby the amount of water diverted to'thebowl rim may be regus lated or it maybe entirely cut off for cleaningpurposes. The member is provided at itsupper end with a clean out plug11.

It willibenoti'ce'd that the ball valve 'ch'am-,

' offset from the portleading "into 'thelower end of the, leg 5 thearrangement being such that when the water lifts the valveflt moves .toone side and allows unobstructed passage'ofthe contents otthe bowl underthe flushing action.

, passage from the bowl, a water'jet for said andbowl; g V r 2. In awater .closet, a bowl,'adischarge pipe connected to the bowloutlet,'aiwat'er indischarge passage, and a valve between the jetejector discharging into said discharge pipe,

- and a check valve interposed between the'im 'j'ector and bowl-"outlet.
